radius = 31
angle = π/6
length of an arc = ??
length = π/6*360 * 2*22/7*31
= π/6*180*22/7*31
= 1/π*6*180*22/7*31
= 7/22*6*180*22/7*31
= 6*180*31 = 33480
angle = π/6
length of an arc = ??
length = π/6*360 * 2*22/7*31
= π/6*180*22/7*31
= 1/π*6*180*22/7*31
= 7/22*6*180*22/7*31
= 6*180*31 = 33480

length of arc = angle×radius
where angle is in radian
length= (π/6)×31 = 16.23
where angle is in radian
length= (π/6)×31 = 16.23
